It's a beautiful place and a dreamlike landscape. What a shame the shelter isn't working. These politicians we have don't do a single thing right.

Mountain pass, the Puerto de Las Señas is one of the best-known ascents in Castilla y León. Almost 3 km long, the climb reaches 1627 masl.

The tunnel was carved by hand through which in the past the animals had to be unloaded so that they could pass through. Now, it is somewhat wider and allows tractors etc. to pass. Without a doubt, it is the most spectacular area of the route, with impressive vertical precipices.

The viewpoint is in the heart of the Redes Natural Park. From Bezanes there is a path that leads to the braña de Brañagallones and that will allow you to approach this natural balcony, with one of the best views of the park. The masses of La Rapaona and Peña del Viento stand out.

Be careful, the climb from Belerda is really strong, sections of 23% and terrain in fair condition, forest track for livestock use within the Redes Natural Park. Only access by walking or cycling.

The initial part of the route, starting from Bezanes, is the hardest part, hold out until the Crestón tunnel and the climb is yours.
